Tina’s life takes a shocking turn when she notices a birthmark on her best friend Megan’s adopted son, Shawn, identical to the one her deceased son, Liam, had. Overcome with emotion, she becomes convinced that Shawn might be her son. “Could Shawn really be my Liam?” Tina wonders.
Tina hires a private investigator to uncover the truth. She asks Megan about the adoption, but her suspicions grow when Megan is evasive. “Why are you asking all these questions?” Megan asks, worried about Tina’s obsession.
A breakthrough comes when the investigator discovers that a nurse involved in Tina’s delivery also facilitated Shawn’s adoption. Tina confronts Megan at the airport, begging her not to leave with Shawn, declaring, “He’s mine. I know about the nurse.”
After a DNA test confirms her suspicion, Megan confesses she had doubts but ignored them out of fear. In a bittersweet conclusion, Tina and Megan agree to share custody of Shawn, rebuilding their lives around a redefined family.
